IMPROVEMENT IN PRINTING PRESSES.

@In ,rlgrhnlc numb tu in tlgrsi tittus ntmt :uit mating peut at the sinne TO ALL WHOM IT MAY CONCEBN.: i

Be it known that I, JOHN HENRY, of Jersey'City, in the county of Hudson, and State of New Jersey, have invented a certain new and useful Improvement in Printing Presses, of which `the following is full, clear, and exact description, referenco being had to the accompanying drawing, forming part ofV this speciliv cation, land in whichi i Figure 1 is a side elevation of a cylinder press in part only, illustrative of my invention ;4 and Figure i?, a plan thereof, with the cylinder removed. Like letters refer to like parts in both figures.

My invention relates to the ink-distributing apparatus, and the nature of it consistsin a combination with a table-distribnting surfaeeef a peculiar arrangement of disk distributors; also, in a novel mode of operating the disks, said invention embracing a separate fountain to each distributor or system of distributors, for the` purpose of dealing out heavy ink in minute quantities. Disks, I am aware, have before been used as distributors, both single revolving onesand a. combination. of concentric disks, moving in reversed directions, as substitutes for the French tableg `but they do not present the same convenient surface as does a table-distributor, while my improvement possesses the advantages ofboth systems. i -i i For the information of others whom it may concern,.I will now proceed to describe my invention, with reference to the drawing v i i A i A represents the cylinder of a Napier press, and B the reciprocating1 bed or table, both of which maybe operated 'in the usual manner or by the ordinary means, which, as' well as other parts andmotions not illustrated in the drawing, it is unnecessary for me here to refer to. It may, however, herebe remarked that `to secure perfect register the drum or cylinder A has the ordinary shorteireular racine, at both ends, and the bed'B` a rack, t, on both sides, these .latter being made adjustable so as to be readily controlled by the Pressman. When in gear,'that is, the racks on the 'drum with the racks on the bed, before and at the commencement of an impression, there is by this arrangement none of thatone-sided strain which takes place where thedrum and bed are geared on one side only, which, by reason of unequal wear, makes it so diieult to keep the press in register. The machine partly represented in the drawing, though onlyshown with four inking rollcrs,c d, e,f, I prefer saould be built for six, the bed B being suliciently elongated, and cylinder A correspondingly enlarged to enable the six rollers to clear a full form, as also to give both systems of distribution time for separate action. C is the Frenchtablc, on which are arranged one,two, or more disks, D, the upper faces ofl which lie llnsh'with the top of the table in which they are made to partially turn at intervals, that is, when outside of the end distributing rollers g, t, which receive their supply from the roller`z above, and fountain roller,j, of the one fountain E. These disks, thus operating, materially assist the table-distributing rollers `to perform their function. represents the form or fornibsuluace.` F is an inner fountain arranged over the inking rollers e, d, e, f, or thcrea-bouts, and, in communication therewith by rollers c and l, and the usual intermediate or additional ones. .Between the inking rollers and end distributing ones, the usual` diagonal distributing rollers m m, of which thereinay be four', are arranged. Here, it will be seen, are embraced two different systems of distribution, or, as it may be termed, two kinds of distributors,l each operating to advance Athe work cr action of the other, and combining the advantages and conveniences of both the table and `the, disk, drawing,

too, fromv separatefountains, wherebyheavy ink may be doled out in very minutequantities, each system of distribution aeting'sep-,irately dnringevcry revolution of the cylinder', and at the required moment communicating their respective quantities of ink to the inking rollers, each of which should clear the full forni. lilo otherwise distribute very line stiff ink, for fine work, is difficult or a slow process; but by thus causing each fountain to contribute only one-half the inkneeessary for the inkingv rollers, and by the combined actionof the disk and table distribution, including that of the diagonalrollers, the stiifest ink may beiworked witlrmoderate rapidity, perfect Idistrilmtiori effected, and the inking,r rollers properly and evenly supplied. To givethe' necessary turning action to the disks D D at or about the termination of the one stroke of the bed or table, to distribute the ink, each' disk is provided on its under face with a circle of ratchet-teeth, riz, intowhich a pawl, o, gears. This pawl is pivoted at r to a lever, p, which has its fulcrum, q, in a standard attached to tlic bed or table, sai-'l pawl being weighted at the opposite end to that which genre with the disk' and lever `thatcarries' it,

having at its end a. roller, t, so that as the table approaches the end of its stroke, the roller t, in striking and running up an inclined plane, S, causes the lever, p, to work the pawl o, andwith it the disk, the '.ever p being,r returned to its original position in the opposite .motion of the bed by the spring u, acting on the arm s, While the pawl being Weighted, retains its contact with the ratchet formationon the disk during both motions of the bed, though only driving the disk at the close of one. This forms a smooth 'and efficient mode of operating the disks.,

What I claim as new and useful, and desire to secure by Letters Patent, is 1. The arrangement, in combination with the reciprocating distributing table C, of disk distributors D D, for action in concert with distributing rollers, substantially as specified. i

2. The combination with the inking rollers, distributing rollers, table C. and disks D D,.ofv separate foun tains E F, essentially as and for the purpose or purposes herein set forth.
